Let the speed of the boat in still water and the speed of the current be ‘x’ km/hr and ‘y’ km/hr, respectively Upstream speed of the boat = (x – y) = 120/12 = 10 km/hr Or, 25 – y = 10 Or, y = 25 – 10 = 15 km/hr Therefore, downstream speed of the boat = 25 + 15 = 40 km/hr Required time taken = 160/40 = 4 hours
